Description

Side ball {A DRAIN AT SLOPE}

The present invention is a slope safety measures to secure a smooth drainage to prevent the inflow of rainwater into the lower slopes during rainfall in road slopes, tunnel tunnels, housing site construction, etc., anyone can easily construct It relates to the ridge side opening that ensures the safety of the slope even after construction.

Conventionally, the basic structure of the ridged side opening is variously classified according to its use, form, and manufacturing material. In the case of PE products, as shown in FIG. 1A, the main body 101, the flooring material 102, the locking plate 103, and the main body reinforcement material 104 are provided. ), The bottom reinforcement 105, the watertight reinforcement bottom joints 106, the support material 107, the watertight reinforcement joints (108).

However, in the case of concrete products, as shown in Figure 1b is composed of a bottom portion 201 and both side wall portion 202 and a coupling coupling portion 203 formed on one side of the structure is relatively simple. The characteristics of each component are that the main body and the flooring material are used to drain the rainwater, and a device for protecting against leakage and buoyancy is usually included, and the flooring material is a reinforcing fiber which is different from the main body in the material of the parts constituting the existing product. It is made of mixed concrete, and the brace and floor reinforcement can be made of material to preserve its shape in order to meet the purpose of the side opening, and the watertight reinforcing joint material prevents water leakage in the process of draining to the side. Waterproof material is suitable because it is used.

When explaining the construction method of the existing side hole as described above, first excavate the required space for the installation of the side hole, installation of the side hole (made of ready-made products or cast-in-place concrete), and construction of the excavation part backfilling and compaction do.

However, in the series of installation process for installing existing side products and field casting side outlets, only the top side of the side wall part can be backfilled, and the backfill of the bottom side and surrounding ground cannot be made smoothly. Rainfall that flows down the surface of the ground cannot flow into the sidewalls, and scours in the surrounding grounds cause a step at the connections between the sideways and the grounds, and a considerable amount of rainwater flows into the lower slopes through the sidewalls and the bottoms. When rainwater flows into the slope, the unit weight of the ground increases, the strength of the ground decreases, and the safety factor of the slope decreases significantly, thereby threatening the collapse of the slope.

Due to these problems, they are fully familiar with the workers during construction of the sideways, but the side openings are not installed correctly due to the uncertainty of construction due to the lack of understanding of the worker and the lack of theoretical background. The reality is that there is a lack of complete construction management such as becoming useless.

Particularly, in the case of the currently recommended on-site casting, it is almost impossible to construct high and large slopes, it consumes a lot of air and manpower, and it is necessary to move the equipment for on-site casting to the upper part of the cut-off slope as needed. In most cases, the problem after the construction of existing sidewalls is that most of the rainwater flowing down from the slopes during rainfall falls into the sideways, but the weak ground around the sideways is preferentially scoured and the compaction is not smooth. Erosion is triggered and a step occurs in the connection between the side port and the ground.

As a result, rainwater eventually flows into the lower side of the mouth, which increases the unit weight of the ground which forms the slope, and decreases the ground strength, which leads to the burial accident that causes the slope to collapse.

The present invention relates to a side opening for solving the problems occurring after the existing side opening installation, drainage mat (non-woven fabric) to prevent the loss of perforated wall and fine grains on the upper side of the side wall of the upper slope simply assembled on site The purpose is to prevent the large slope collapse by preventing the step between the side port and the ground due to the erosion, scour, and compaction of the surrounding ground in the future by increasing the backfill height to the top of the perforated wall. As well as other purposes, the same effect can be obtained by simply attaching the perforated wall and drainage mat to the existing side of the site and adding the soil backfill and vegetation. It can also be used as a reinforcement measure, which can be applied as a measure to secure the stability of the existing slopes. It aims to provide a gutter which is largely expected utilization.

The present invention is to prevent the inflow of rainwater into the lower slopes during rainfall in road slopes, tunnel openings, housing site construction, etc. as a side opening that can ensure the slope safety while ensuring a smooth drainage channel 2a and As shown in Figure 2b is composed of a bottom surface (A1) and both side walls (A2), and the lid engaging jaw (A3) is formed in the upper inner side of both side walls (A2), and the upper surface of one side wall (A2) at regular intervals ( A portion of the support coupling rod A5 is fitted into the hole A4 of the drain pipe A through which A4 is drilled, and a plurality of verticals formed perpendicular to the horizontal frame B1 to the remaining protruding support coupling rod A5. Since the frame B2 is orthogonal to the receiving frame B3, the remaining partitions are formed of perforated plates B4, and the coupling protrusions B5 and the coupling grooves B6 are formed on each of the vertical frames B2 on both left and right sides. ) Is formed on the back of the perforated plate (B4) Non-woven fabric may be combined into a number of grid-side hole (B2 ') with drilled directly below the vertical frame (B2) of the inclined support plate (B) of (B7) is attached.

In another embodiment of the present invention, as shown in Figures 3a and 3b is composed of a bottom surface (C1) and both side walls (C2), the capping jaw (C3) is formed in the upper inner side of both side walls (C2) and the upper Several vertical frames (D3) formed perpendicular to the upper and lower horizontal frames (D1, D2) on the bolts (C4) of the drain pipe (C) in which several bolts (C4) are fixed to the outer side of the side wall (C2) toward the inclined surface The partition portion is formed of a perforated plate (D4) is formed in the upper plate of the left and right vertical frame (D3) engaging projections (D5) and engaging grooves (D6) are formed in each of the lower half of the vertical frame (D3) Two binding holes D7 are drilled and the binding holes D7 formed on the inclined surface support plate D to which the nonwoven fabric D8 is bonded to one side of the perforated plate D4 are inserted into the binding holes D7. It can be called a side ball.

The previous embodiment is a means for connecting the support A5 to the hole A4 formed in the drain pipe A and the hole B2 'formed in the inclined support plate B. The latter uses a bolt fixed to the outer surface of the drain pipe. It is a means for inserting the binding hole formed in the lower half of the vertical frame of the inclined support plate (B) to bind with a nut.

The drain pipe (A) can be a concrete or plastic material that is commonly used, and the inclined surface support plate (B) is formed integrally with synthetic resin material, which is advantageous in terms of security and installation, and the support coupling rod is made of steel, and the nonwoven fabric passes easily through water. It is good to be able to.

The construction method of the side opening first excavates a trench of a certain size in consideration of the drainage pipe size and construction characteristics to install the drainage pipe and installs or installs the drainage pipe, and then the side wall (A2) of the upper inclined side drain pipe (A) Insert a part of the support coupling rod (A5) into the hole (A4) in the hole, and then insert the inclined surface support plate by inserting several holes (B2 ') formed in the inclined support plate (B) in the remaining part, and after installing the side opening of the excavation part, surplus Construction is completed when the vegetation is carried out after filling the excavation portion and compacting the earth and sand on the inclined support plate (B) on the upper inclined surface side. (4a and 4b is an installation state diagram of the side opening according to the present invention)

This side port is installed on the inclined support plate on the side wall of the upper slope of the drainage channel, so that the slope is filled with earth and sand by the height of the inclined support plate, so that water flowing down from the inclined surface during the rainfall erodes the boundary between the side wall of the drain and the slope. This prevents scour from occurring at the bottom or around the drainage channel, and the nonwoven fabric-inclined support plate also weakens the strength of the water flowing down the upper slope, causing water to seep into the drain through the nonwoven fabric. Ground collapse and landslides can be prevented.

The side opening according to the present invention can prevent the collapse of the slope because rainwater that flows from the inclined surface into the side opening does not penetrate into the lower side of the ground, even in the case of rain, it is possible to prevent a large investment accident.

By filling the soil by the height of the perforated wall, even though the surrounding ground was compacted somewhat poorly during construction, the rainwater flowing down from the upper slope flows into the side opening through the perforated wall along the surface, so the surrounding ground is lost. And it can prevent the phenomenon that rainwater flows into the lower ground.

In addition, since the drainage mat is installed on the rear surface of the perforated wall, it is possible to prevent the sediment of fine grains from being lost, thereby minimizing the loss of soil due to rainwater, which is very helpful for the greening of slopes. can do.

In this construction method, by constructing the perforated wall slightly higher than the back soil, it is possible to prevent the soil, small stones, etc., rolled down from the upper slope to prevent the drainage from delaying and poorly draining the drainage drainage. Not only is it a great help, but its construction method is simple, but its function is excellent, so it can be said to be a highly applicable side ball as a safety countermeasure method of slope.
